Difficulty: HardVerbs, Tenses, and Aspect

Which verb form correctly completes the sentence below to express a hypothetical past condition?

Answer:Had the chief forensic auditor 【uncovered】 the discrepancies in the financial ledgers earlier, the board would have prevented the severe loss.

Answer

The past participle verb form 'uncovered' (or 'discovered' / 'detected' / 'identified') correctly completes the inverted past perfect clause.
In an inverted third conditional clause where the conditional marker 'if' is omitted, the auxiliary 'Had' moves to the initial position before the subject and must be followed by a past participle (such as 'uncovered') to form the past perfect aspect matching the result clause ('would have prevented').

Step-by-Step Solution

1
Identify the clause structure and conditional type.
The sentence opens with an inverted conditional structure initiated by the auxiliary verb 'Had' without the conjunction 'if'.
An inverted third conditional structure places 'Had' before the subject to express an unfulfilled past hypothesis.
2
Determine the required grammatical form for the main verb following the auxiliary.
The past perfect construction demands the past participle form of the main verb (e.g., 'uncovered').
In third conditional sentences, the condition clause requires the past perfect aspect ('had' + past participle) to pair grammatically with the perfect conditional result clause ('would have prevented').
